Djk,
yes and I would include these in the repair.

You can't do anything about a single family home, unless it is rented out. I agree with Paul there. Any requirements would have to apply to the point of time when the house changes owner. (Darn, I just can't write a sensible sentence. [Linked Image] )

But for rented homes and multifamily homes, it's not just your home you are putting at risk. I don't see anything strange about forcing everybody to rewire. When it comes to plumbing, ventilation and gas the cost of fixing the building at once is far less than fixing it flat by flat.

The best way is to go is the insurance company. It is enough that the authorities are concerned with cases where the neglect is such that it is an immediate danger. (Like today)
